TINV
Calculates the inverse of the two-tailed TDIST function.
Syntax:
TINV(p; r)
- returns the value x, such that TDIST(x; r; 2) is p.
- r (degrees of freedom) is an integer >=1.
- p (probability) must be >=0 and <=1.
- To calculate the inverse of the one-tailed TDIST function, use TINV(p*2; r), which returns the value x, such that TDIST(x; r; 1) is p.
Example:
TINV(0.666; 2)
- returns approximately 0.50.
